The Reserve Bank of India’s decision to increase the repo rate by 25 basis points to 5.50% has renewed attention on borrowing costs, investment strategies and financial planning across India’s renewable energy, infrastructure and real estate sectors. The move marks the first interest rate hike in more than three years, reflecting the central bank’s efforts to address inflationary pressures and manage global economic uncertainties. Industry leaders view the increase as a manageable adjustment that is unlikely to derail India’s long-term investment and economic growth momentum.
The renewable energy sector, which requires substantial upfront investment and long-term financing, could experience some pressure from higher borrowing costs. Solar, wind, and energy storage projects generally depend on significant debt funding, while electricity tariffs are often fixed through long-term power purchase agreements. Consequently, even a small increase in interest rates can affect project economics, particularly for developers operating with high debt levels and limited profit margins.
A 25-basis-point increase could add approximately two to three paise per unit to electricity costs for certain highly leveraged projects, depending on their financing structure and other project-specific factors. Although the immediate impact may be limited, developers will need to consider the possibility of higher financing costs when preparing bids, arranging loans and evaluating future investments.
Companies that have relied on aggressive bidding and narrow margins may face greater pressure on equity returns. In contrast, developers with strong balance sheets, diversified funding sources and stable contracted revenues are better positioned to manage changes in borrowing costs. Efficient procurement, standardized project designs and timely execution could also help companies control expenses.
Despite these challenges, India’s renewable energy investment outlook remains supported by rising electricity demand, industrial expansion and the country’s growing clean energy requirements. Energy storage systems, battery integration and hybrid renewable projects are expected to attract continued attention as commercial and industrial consumers seek reliable electricity supplies and lower long-term energy costs.
Industry observers also point out that project risks extend beyond interest rates. Delayed payments from power distribution companies, uncertainty surrounding power purchase agreements, transmission constraints, and difficulties in securing reliable offtake can have a greater impact on project financing and profitability. Addressing these issues remains essential to maintaining investor confidence and accelerating renewable energy deployment.
The rate increase could also influence investment decisions in infrastructure and real estate. Commercial and logistics property markets are increasingly attracting capital toward assets supported by genuine occupier demand, long-term leases and established business requirements. Rather than depending mainly on rising property valuations, investors are prioritizing stable income and operational performance.
In the residential market, higher home loan rates could increase monthly repayments for new borrowers and modestly affect affordability. However, long-term housing demand and the expansion of global capability centres continue to support real estate activity in major urban markets.
From an analytical perspective, the repo rate increase is likely to encourage greater financial discipline across capital-intensive industries. Renewable energy developers may need to reassess debt-equity ratios, financing tenures and bidding assumptions to protect returns. Companies that combine prudent financial planning with efficient project execution are likely to remain more resilient.
The broader interpretation is that the impact of higher interest rates will vary according to individual business models, financing structures, and market conditions. While highly leveraged projects may face tighter margins, the overall clean energy transition continues to benefit from sustained electricity demand and long-term investment requirements.
Aditya Goyal, Head Finance & Accounts, Hexa Climate: A 25 basis point hike is manageable for renewable project finance. The more important signal is the direction of rates. We price project debt over a 15-to-20-year horizon, through the construction drawdown and at least one refinancing, so lenders react to where they expect rates to settle rather than to a single repo move.
In tariff terms, 25 basis points on a project with about 75% debt adds roughly two to three paise per unit. That is a real cost, but it does not change the viability of a well-structured project. Lenders still see operating renewable assets with creditworthy offtakers as low risk, and borrowing costs for these assets have historically moved much less than broader lending rates.
The bigger driver of our cost of capital is counterparty and offtake risk. Delays in signing power sale agreements, late payments, and uncompensated curtailment add far more to the cost of debt than this rate decision. For developers, the sensible response is to secure longer tenors and diversify funding sources. For the sector, the greater gains will come from resolving the off-take risk.
Sunil Sharma – Sr Director & Head, Project and Corporate Finance, AMPIN Energy Transition – A 25 bps hike won’t stop anyone building renewables, but it tells us rates have turned. In a business where you invest almost everything upfront and live off a fixed tariff for 25 years, that matters. NBFC and infra lenders’ funding costs are already up, and they’ll pass it on within a quarter or two. Bank MCLRs move more slowly. In 2022–23, it took over a year for a 250 bps repo hike to show up as about 155 bps. The developers who should worry are those who bid thin tariffs assuming cheap money would last, because every rise in interest costs comes straight out of equity returns. Those who refinance early, lock in longer-tenor or green bond funding, and spread their lenders will manage. I expect bidding to become more disciplined, not the cycle to stall.
“The RBI’s 25 basis point hike and shift to calibrated tightening point to a more cautious rate environment, and for capital-intensive renewable projects this means some near-term pressure on financing costs. The fundamentals, however, remain strong. Industrial demand for reliable, cost-competitive clean power continues to grow, and long-term contracted revenues give well-structured projects resilience through rate cycles. At Oyster Renewable, our focus remains on disciplined capital structuring, prudent deployment and execution efficiency to sustain investment momentum.”– Sandeep Arora, Chief Financial Officer, Oyster Renewable Pvt. Ltd
“The RBI’s upgrade of FY27 GDP growth to 7.1% reflects a resilient economy and provides a positive backdrop for continued investment in infrastructure and the energy transition. For an EPC business like ours, the 25-bps hike to 5.5% will add some pressure on working-capital and project financing costs, but demand for solar, from utility-scale and industrial projects to rooftops, remains strong. As project volumes increase, EPC players can benefit from better procurement, standardisation and execution efficiencies, helping offset cost pressures and making renewable projects increasingly competitive. Sandesh Naik, Chief Financial Officer, AB Energia
“The current rate environment is likely to bring greater discipline to real estate, with investors placing greater emphasis on the quality and durability of underlying cash flows rather than relying on valuation expansion. This makes sustained leasing demand, occupancy, and the ability of an asset to deliver long-term value increasingly important. For commercial and logistics real estate, this also reflects a larger shift in how businesses view these assets. Well-located, integrated developments are increasingly becoming part of the operational infrastructure of businesses, supporting supply chains, workforce needs, and market access. As a result, we expect capital to favour assets that are backed by genuine occupier demand and have a clear economic role, rather than being driven purely by the liquidity cycle.” Neeraj Balani, Chief Customer Officer, Welspun One
“The RBI’s decision to raise the repo rate by 25 basis points to 5.50% reflects the need to contain inflationary pressures arising from global uncertainties. The aspiration to own a home continues to support housing demand, though even a modest EMI increase puts some pressure on a family’s monthly budget. Buying a home remains a cherished aspiration and a long-term commitment.” Harshavardhan Neotia, Chairman, Ambuja Neotia
Tanmoy Duari, CEO, AXITEC Energy India Pvt. Ltd.: “The RBI’s decision to raise the repo rate by 25 basis points to 5.50% reflects a measured response to the evolving inflationary environment and heightened global uncertainties. While tighter financial conditions may have a near-term impact on borrowing costs and investment decisions, the RBI’s continued confidence in India’s growth outlook is encouraging for the broader economy.
For the renewable energy sector, policy stability and access to competitively priced capital remain important enablers of long-term investment. As India continues to pursue its clean energy and energy-transition goals, maintaining a balance between inflation management and growth-oriented capital formation will be critical.
The upward revision of the FY27 GDP growth projection to 7.1% also underlines the resilience of the Indian economy. We remain confident that India’s strong fundamentals, growing power demand and continued focus on renewable energy will support sustained investments in solar and other clean-energy infrastructure”
Arman Puri, Director, Hindustan Power, “The first rate hike in over three years was expected. The more important signal is the shift to calibrated tightening, which tells developers to plan for a cycle of increases and not a single move. Power and infrastructure projects are financed largely through long-tenor debt, so the cost of capital flows directly into the cost of electricity.
A 25 basis point increase is absorbable and does not change project economics on its own. What the sector must now do is price upcoming bids and financing plans for a higher-rate environment. Electricity demand continues to grow strongly, and that will keep capital flowing into new capacity.”
Simapreet Singh, Executive Director and CEO, Hartek Power, “India’s clean-energy buildout is only as strong as the capital supporting it. A 25-basis-point rate rise may appear modest, but in capital-intensive projects, higher borrowing costs pressure equity returns and tightly bid tariffs. Developers will scrutinise project economics closely, particularly in BESS and green hydrogen. However, this does not alter the direction of renewable energy in India. Investment in renewable generation, smart grid solutions and storage remains essential. Financing must evolve alongside infrastructure through green bonds, blended finance and longer-tenure debt. At Hartek Power, among the top solar EPC companies in India, we remain focused on disciplined execution”
Manoj Patel, Founder & CMD, Solaryaan: The RBI’s 25-basis-point rate hike could push up financing costs for energy projects and prompt businesses and consumers to assess investment decisions more carefully. This makes demonstrable savings, consistent performance, and long-term value even more important.
At Solaryaan, our focus is on making energy independence more practical and accessible through solar and hybrid energy solutions. Hybrid inverters combine solar generation, battery storage, and grid power, helping customers make greater use of their own solar energy and, when paired with suitable batteries, have backup available during power cuts. For businesses that depend on diesel backup, these systems can also help lower fuel usage.
While higher borrowing costs may influence the timing of certain investments, the need for affordable and dependable energy remains strong. We believe solutions that offer measurable savings and dependable backup will continue to play a meaningful role in India’s clean energy transition.
Ankit Patidar, Shakti Pumps (India): The RBI’s decision to raise the repo rate by 25 basis points to 5.5% comes against the backdrop of efforts to maintain macroeconomic stability while supporting India’s long-term growth trajectory. While there may be a marginal increase in borrowing costs in the near term, we do not see this having a material impact on the strong investment momentum across India’s energy and renewable sectors.
India is in the midst of a structural transformation of its energy landscape, driven by rising power demand, renewable capacity expansion, energy security, domestic manufacturing and continued government support and policy measures. These fundamentals remain extremely strong.
For well-capitalised companies and projects with strong fundamentals, a modest change in the cost of capital is unlikely to alter long-term investment decisions. Instead, it can reinforce financial discipline, operational efficiency and a focus on quality projects.
We remain highly confident in India’s capex cycle and believe investments across solar, energy storage, power infrastructure and energy-efficient technologies will continue to gain momentum. With greater access to green finance and innovative financing mechanisms, India remains one of the world’s most attractive markets for long-term clean-energy investment.
The RBI’s 25-basis-point repo rate increase to 5.50% presents a manageable financing challenge rather than an immediate threat to India’s renewable energy and infrastructure growth. The decision highlights the importance of disciplined capital allocation, stronger financial structures and operational efficiency. For developers and investors, maintaining profitability will increasingly depend on managing project risks, securing reliable revenues, and delivering projects efficiently in a changing interest rate environment.
